To determine the value of sonography in the evaluation of acute traumatic tears of the rotator cuff.
Preoperative sonography was performed within 3 weeks of trauma in 184 patients, 98 of whom underwent surgery. The rotator cuff tears were preoperatively classified as partial-thickness tears or as small, large, or massive full-thickness tears. Sonographic findings were correlated with surgical findings (n = 70) and arthroscopic inspection (n = 28).
Adequate examination was possible in 163 (88%) of 184 patients. Sonography demonstrated 42 (91%) of 46 full-thickness tears and seven (78%) of nine partial-thickness tears. Sonography showed more extensive tears than were found at surgery in four (4%) of 98 patients and less extensive tears in seven (7%) of 98 patients. Sonographic patterns were a defect (31 [63%] of 49 tears), focal thinning (10 [21%] of 49 tears), and nonvisualization (eight [16%] of 49 tears).
Sonography is useful in the evaluation of acute shoulder trauma when a rotator cuff tear is suspected and findings at plain radiography are negative.
确定超声检查在评估肩袖急性创伤性撕裂中的价值。
对184例患者在创伤后3周内进行术前超声检查，其中98例接受了手术。术前将肩袖撕裂分为部分厚度撕裂或小、大或巨大全层厚度撕裂。超声检查结果与手术结果（n = 70）和关节镜检查结果（n = 28）进行相关性分析。
184例患者中有163例（88%）能够进行充分检查。超声检查显示46例全层厚度撕裂中的42例（91%）和9例部分厚度撕裂中的7例（78%）。在98例患者中，超声检查显示的撕裂范围比手术中发现的更广泛的有4例（4%），比手术中发现的更不广泛的有7例（7%）。超声图像表现为缺损（49例撕裂中的31例[63%]）、局灶性变薄（49例撕裂中的10例[21%]）和无法显示（49例撕裂中的8例[16%]）。
当怀疑有肩袖撕裂且X线平片检查结果为阴性时，超声检查对评估急性肩部创伤很有用。
